Concrete work tops

[GB_Groundworks]

Helping my mate do some for his new cafe/bakery

Anyone had any experience offer any tips?

I know a lot about slab finishing etc

Mixes? 6mm aggregates, chicken wire?

I have this book somehwere
aggregate and slump is mega important and also a very good shuttering chippy
think it has to be thicker then you imagine around 70mm IIRC

Have seen it done on grand designs. It looked fantastic when it was all polished, but they never revealed the exact process. Had glass in it if I recall

I read the book and its bloody complicated,however with the right chippy and the right mix can look fab

plunge saw for shutters



this is the first one before the poly fibres had arrived



white spa aggregate in it so we can grind it back



battery akita poker let me down so had to try using hand sander to vibrate it

first go



wonderfuly smooth but some cavities in it but my mates mrs loves it says it adds to the industrial charm, i wasn't best pleased with it





going to get some clear resin off my mate and fill in the voids and seal it, made a test piece tonight to try them out

also ordered a wet grinder to take it back if we need to and then fill with a cement slurry if they want perfectly smooth

stripped out the second one, better mix on this with fibres not mesh









using the conti board the concerte is very smooth but got 50-6000 grit diamond pads

fitting apiece of wood in-between as a contrast, picking that up tomorrow and wet grinder has arrived so can grind them back tomorrow.

although rubber backer pad won't thread onto spindle didn't expect much for £140 though!

got few phone calls into sealant companies looking for a good sealant thats not irritant or toxic!
